1 Chronicles 25:6-8

New Revised Standard Version Catholic Edition

⁶ They were all under the direction of their father for the music in the house of the Lord with cymbals, harps, and lyres for the service of the house of God. Asaph, Jeduthun, and Heman were under the order of the king. ⁷ They and their kindred, who were trained in singing to the Lord, all of whom were skillful, numbered two hundred eighty-eight. ⁸ And they cast lots for their duties, small and great, teacher and pupil alike.
